What is the perl equivalent to grep -c

Suppress normal output; instead print a count of match-
ing lines for each input file. With the -v, --invert-
match option (see below), count non-matching lines.

Hi,
I'm working with gawk (on DOS) today.
A goal is: find a string for-instance '123', cut a line in two columns and write second one. The problem is: command line works OK, awk file doesn't. But I would like to work with file because there are many strings to find.

I'm looking for SED equivalent for grep -w -f. All I want is to search a list of patterns from a file. Also If the pattern doesn't match I do not want "null returned", rather I would prefer some text as place holder say "BLANK LINE" as I intend to process the output file based on line number.

docbook2texi-spec.pl
DOCBOOK2TEXI-SPEC.PL(1) DOCBOOK2TEXI-SPEC.PL(1) NAME
docbook2texi-spec.pl - convert DocBook Booksto Texinfo documents SYNOPSIS
sgmlspl docbook2man-spec.pl nsgmls [ sgml document ]| sgmlspl docbook2texi-spec.pl [ basename ] DESCRIPTION
docbook2texi is a sgmlspl spec file that produces GNU Texinfo documents from DocBook documents. The program reads ESIS produced by nsgmls (or other SGML parsers) from standard input. Currently the document element must be Book, other- wise the results are undefined. Its output, the converted Texinfo document, is written to standard output. The file basename.refs will also be created, which contains all the nodes in the document and their immediate 'child' nodes. As node pro- cessing always require forward references, docbook2texi must be run twice for each document: the first time to build the references, and the second to actually generate a valid document. REQUIREMENTS
The SGMLSpm package from CPAN. This package includes the sgmlspl script that is also needed. LIMITATIONS
Trying docbook2man on non-DocBook or non-conformant SGML results in undefined behavior. :-) This program is a slow, dodgy Perl script. This program does not come close to supporting all the possible markup in DocBook, and may produce wrong output in some cases with sup- ported markup. TO DO
o How the hell do you represent a backslash () in Texinfo!!@? I've tried \ but TeX complains about it. o Fix breakages found in the test documents. o Add new element handling and fix existing handling. Be robust. o Make it faster. I think most of the speed problems so far is with parsing ESIS. Rewrite SGMLS.pm with C and/or get input directly from SP. o There are some dependencies on elements occurring when they are actually optional (according to the DTD). We need to fix that (prefer- ably) or prominently state the requirements. o Allow other more common document elements. o Separate out node referencing to a separate script. Not only would it make it faster/easier to maintain because it's separate from the main code, but also I would like it to evolve into an automatic DocBook ToC generator. COPYRIGHT
